PMB 120 – High-Elasticity Polymer Modified Bitumen for Extreme Load Performance

PMB 120 is an advanced-grade Polymer Modified Bitumen engineered for projects that demand exceptional elasticity, durability, and resistance to deformation under the heaviest traffic conditions. Its formulation allows for superior performance in both scorching summers and freezing winters, ensuring roads and industrial surfaces maintain integrity over decades.

Designed with cutting-edge polymer technology, the 120 provides a level of structural resilience and flexibility that far surpasses conventional bitumen grades, making it a preferred choice for critical infrastructure around the world.

What Makes PMB 120 Stand Out

The unique composition of PMB 120 gives it a competitive edge in challenging environments. Core benefits include:

• Extreme Load Resistance – Maintains shape and stability under constant heavy pressure.

• Superior Fatigue Life – Resists cracking from repeated load cycles.

• Unmatched Elastic Recovery – Bounces back to original form after deformation.

• Stable Across Temperature Ranges – Performs in both tropical heat and sub-zero winters.

• Outstanding Adhesion – Strong aggregate bonding, even in wet conditions.

Key Applications of PMB

1. Mega-Highways and Express Lanes

Perfect for continuous heavy freight and passenger traffic, ensuring minimal maintenance over time.

2. Container Terminals and Ports

Withstands constant movement of cranes, forklifts, and container trucks.

3. Large-Scale Industrial Yards

Resists rutting and surface fatigue from slow-moving heavy machinery.

4. Mountain and Cold-Climate Roads

Handles sharp temperature swings without cracking or brittleness.

5. Airport Runways

Provides stable, smooth, and safe surfaces for high-impact aircraft landings.

Advanced Manufacturing of PMB 120

The production of PMB 120 is carried out under strict quality control to guarantee consistency:

1. Base Bitumen Selection – High-quality paving grade chosen for compatibility.

2. Polymer Addition – Advanced elastomeric polymers, typically SBS, integrated for maximum flexibility.

3. High-Shear Processing – Ensures uniform polymer dispersion throughout the bitumen.

4. Temperature Precision – Maintains ideal processing conditions to preserve polymer properties.

5. Comprehensive Testing – Includes penetration, softening point, viscosity, and elastic recovery.

Environmental Contribution

By extending the lifespan of pavements, Polymer Modified Bitumen 120 reduces the frequency of resurfacing. This results in lower raw material consumption, reduced energy usage, and minimized CO₂ emissions—supporting sustainable construction practices worldwide.

Frequently Asked Questions (FAQ)

Q1: Can Oxidized Bitumen perform as well as Polymer Modified Bitumen 120 in high-load areas?
A: No. While Oxidized Bitumen offers rigidity, PMB 120 provides superior elasticity and load-bearing capacity.

Q2: Is PMB 120 more flexible than Oxidized Bitumen in cold regions?
A: Yes. Polymer Modified Bitumen 120 retains flexibility and resists cracking even in severe cold, unlike Oxidized Bitumen.

Q3: Can Polymer Modified Bitumen 120 and Oxidized Bitumen be blended for custom applications?
A: Blending is not recommended as it can compromise the benefits of polymer modification.

Q4: Which is better for rut prevention—Oxidized Bitumen or Polymer Modified Bitumen 120?
A: PMB offers far greater rut resistance, especially in high-traffic industrial zones.
